If you are doing something that needs to iterate a billion times, you
shouldn't be using PHP. Things like calculating a fractal is just not
what PHP was meant for. The vast majority of Web apps have absolutely no
need to iterate that many times. You wouldn't try to show a user a
billion database records on a single page, for example. Chances are
pretty good that you are going to iterate less than 1000 times on a
typical request and if you do end up having to iterate more for some
reason, you would probably cache the result somewhere so you don't have
to do it on a subsequent request.
